Ford MOD motors sweep 2013 PHR Engine Masters!

Thanks, Ken, I've seen their web site.  Their prices are awfully high, especially in the small block Chevrolet world.  It would be cool if an FE version of such a head were available - at a reasonable price.

Jay and all,
How about a 3 valve FE head?  Especially if you want to keep the same config for the exhaust ports.  I tried googling Gurney-Weslake and Weslake but didn't see the 3 valve head they developed for the SBF back in the late 60s.  The 2 valve Weslake design was used in Gurney's SBF Indycar engines and of course the same engine/head config won LeMans in 68-69. The site I saw did mention that Mr. Weslake was a big proponent of the heart-shaped combustion chamber and that it was his "trademark".

Just thinking,

I know i have seen some old Engine (probably 1920s) with 4 valves
and "fork" rockers. I dont remember if it was car or
motorcycle engine
[/quot

Suddenly today it hit me where i saw those fork rockers
it was on a Packard Merlin Engine
They got one Engine displayed at the Airport. I was waiting
for the wifes plane to arive so i had plenty of time to study it.
That versions of the Merlin Engines got excentric rocker-
shafts so when you rotate the shaft you change the rocker-
ratio

Say Heo, for a real blast from the past how about a SOHC V-8 engine from.......1914   

That's one to tell folks who claim that overhead cam engines are 'new' technology.....like 99 years ago!

Yes  I saw a 4 cyl Hemi Engine with overhead cam
i Think  from 1903 for those that think Chrysler
"Invented" the Hemi
It was made by Star in USA i think.
Nimbus Motorcycles in Denmark built
almost a copy of it but smaller 500-600cc
or something like that. Cam is driven by a
vertical shaft that is also the generator
For those interested you can google Nimbus Motorcyklar
Interesting Engine in a uggly motorcycle
They were first with telescopic fork

New rules are out for next year.  They did outlaw the 4 valve.
Pretty much had to - considering that nothing else was close - not within 200 points.
Magazine needs variety to write about or the contest would have ceased to exist - and that's not good for anybody.

Other than that, it's very similar to last year with one notable twist.  The scoring will now include a value for peak horsepower and peak torque, along with the averages on each of three dyno pulls.  The peaks are now 1/7th of your score, giving some incentive to the bigger engines with the Hollywood numbers.

The Popular Hot Rodding issue with event coverage just hit the news stands.  Check out the pictures and comments about my FE entry - they were very kind.  Little 433 inch piece ended up making 712 horsepower with 11.5:1 compression, a dual plane intake, and hydraulic rollers - that's 1.64 HP per cube.  Good debut for the CNC ported version of my heads...

Makes you wonder what it would have done at about 13.5:1, with a ported Victor and an 1150, and a nice solid roller- I'd bet a coupla clams we might find out in the near future lol...

Those are really impressive numbers, Barry, congrats on the motor and the coverage.  For those of us who don't have the magazine, would you mind giving us some details?  Flow numbers on the heads for example, what intake, cam specs?  Or is it a secret?

[ScotiaFE]

I see your posting. Good Stuff.

What about cheap ass class. Old used parts with little or no money for fancy parts and machining.
Oh wait that's what I do.

[Barry_R]

No secret anymore...

They will be doing an article on the engine, but I can certainly share some info at this point

First will be head flow data.
These ports are obviously larger than the as cast versions - mainly wider but not all that much taller.  Still very much within porting range on all the normal intakes.  No welding required on the heads - I think this is a nice gain over other medium riser style options that exist.
